DBS3900 system consists of:
RF jumper
This describes the function modules of the DBS3900 system. The function modules are the BBU3900 and the RRU3804/RRU3801E;
BBU3900: Baseband unit. It processes baseband signals and provides the interface between the DBS3900 and the RNC.
RRU: Outdoor remote radio unit. It is responsible for signal processing and transmission between the antenna system and the BBU3836. There are two RRU models of different processing capabilities: the 60 W 4-carrier RRU3804 and the 40 W 2-carrier RRU3801E.
Antenna and feeder system: Antenna and feeder system consists of Antenna, TMA (optional), RF jumper and feeder and so on;

Board
The BBU features a modular-design and can be divided into the following subsystems based on functions: Transmission subsystem, baseband subsystem, controlling subsystem, and power monitoring unit.
When the BBU is fully configured, it involves two WMPTs, six WBBPs or UTRPs, and two power modules. In a typical 3 x 2 configuration, only one WMPT, one WBBP, and one power module are required.
The WMPT board is mandatory for the BBU. A maximum of two WMPT boards can be added for backup. When two WMPTs are configured for mutual backup, the transmission modes of the ports on the boards must also be identical.
The WBBP is mandatory for the BBU. It is used to process the baseband signals. The WBBP supports the connection with the RRU devices only when it is held in slots 02 and 03 of the BBU.
The UTRP is optional. It provides extension transmission interface and can be configured with the UAEC sub-board (ATM and IP protocols supported) and the UPEC sub-board (IP protocols supported).
The UPEA is the power board, which can transform the voltage from -48 V to +12 V; the UPEB is another power board, which can transform the voltage from +24 V to +12 V. Each cabinet can be configured with either of the previous power boards.
The UEIU is the environment interface board of the BBU. The UEIU is used to connect the external monitoring device and transfers the monitoring information to the controlling board. It is mandatory.

Notes
The claimed CE based on net capacity in both the UL and the DL.CCH R99 included, per cell reserved 5CE for downlink and 2 CE for uplink, free for operator.
Resources for Compressed Mode included, not require additional CE.Resources for Softer handover included, not require additional CE.
TX diversity is no impact for CE consumption for both uplink and downlink direction.
R99 and HSDPA have separate processing resources. Resources for HS-DSCH, HS-SCCH and HS-DPDCH included, not affect BB capacity for R99 services.
Extra capacity is added by license keys and/or by adding more boards up to maximum capacity. The step of license expansion is 16CEs according to the customer’s requirements.
